The North Face Assault Bivy is an ultralight shelter for high altitude adventures. The top fabric is a 50D DryWall™ durable polyester ripstop while the bottom is a 70D nylon taffeta, 1500mm PU coated, keeping you dry from the elements. When the weather is dry, use the mesh closure for additional breathability and a touch of air flow through the night. The square cut head and footbox makes tucking in for the evening with a pack and boots much easier, so you don't have to slip into wet gear come morning.
